Insole material is an important factor determining the hygienic properties of shoes. It has a significant impact on health and comfort while wearing them. In this paper, authors describe a scenario of three insole materials: flank leather, cellulose material and composite leather. Quantitative research was done using five upper materials: calfskin full and top grain leather, “buffalo” bovine leather, a soft type of grain leather, and aniline veal skin type “cool”. Qualitative analysis was performed using 3D knitted fabrics as lining. The statistical significance of the differences obtained within the groups analysed is that they prove the impact of insole material on comfort.
